Maintaining the Filter Assembly
Clean the lter regularly. Dirty or clogged lters can greatly
reduce ltering ability and cause a number of system problems
including poor spray patterns, clogged spray tips, etc.
Cleaning
To clean the lter, perform the following procedure.
1. Follow the “Pressure Relief Procedure” found in the
Operation section of this manual.
Filter Cap
Assembly
Filter
Element
w/Ball
PTFE Gasket
PTFE Gasket
PTFE O-ring
Carbide Seat
Filter Body
Spring
2. Remove the lter cap assembly
and spring.
3. Pull the lter element with ball
straight out of the lter body.
4. Clean inside the lter body, lter
element with ball, and lter cap
assembly using the appropriate
solvent.
NOTE: Use care in handling
parts as dirt, debris,
scratches, or nicks
may prevent o-rings or
gaskets from sealing.
This lter element lters from
the inside out. Be sure to clean
the lter element thoroughly
on the inside. Soak in solvent
to loosen hardened paint or
replace.
Inspection
Inspect all parts of the lter assembly before reassembly.
1. Inspect the ball inside the lter element. If the ball has
pressure cuts or scratches, replace the lter element.
a.
If the ball is cut, remove the PTFE o-ring using an
o-ring pick and remove the carbide seat.
b. Check the seat for nicks or grooves. If the seat is
damaged, replace.
NOTE: Removal of the PTFE o-ring will damage the
o-ring and require replacement.
2. Remove the spring from the spring guide on the lter cap.
a. Measure the length of the spring uncompressed. If it
measures less the 3/4” from end to end, replace.
b. Push the spring back onto the spring guide until it
“snaps” back into position.
3.
Inspect the two PTFE gaskets and the PTFE o-ring for
deformity, nicks, or cuts. Replace, if needed.
NOTE: The PTFE gaskets, PTFE o-ring, and spring are
packaged in Filter Service Kit P/N 930-050.
Reassembly
After cleaning and inspecting all parts, reassemble the lter.
1. Place the carbide seat into the lter body. Make sure the
beveled side of the seat is facing up.
2.
Place the PTFE o-ring into the groove on the outer
diameter of the carbide seat.
3. Place the lter element with ball into the lter body.
NOTE: The top and bottom of the lter element with ball
are identical.
4. Push the spring back onto the spring guide of the lter cap
until it “snaps” back into position, if not already done.
5.
Place the thin PTFE gasket onto the step at the top of the
lter body.
6.
Place the thick PTFE gasket onto the top of the thin
gasket.
7. Tighten the lter cap assembly onto the lter body.
Maintaining the Hydraulic System
IMPORTANT: Use of Titan’s Coolflo™ Hydraulic Fluid is
mandatory in the PowrTwin hydraulic system. Do not use
any other hydraulic fluid. Use of any other hydraulic fluid
may seriously damage the hydraulic system and will void
the warranty.
1. Check the hydraulic uid daily. It should be at the
“Full” mark on the dipstick. If it is low, add only Titan
Coolo™ Hydraulic Fluid (P/N 430-361). Never add or
change hydraulic uid except in a clean, dust-free area.
Contamination of the hydraulic uid will shorten hydraulic
pump life and may void warranty.

2. Change the hydraulic uid every twelve months. Drain
the old uid from the tank and ll with 4 quarts of Titan
Coolo™ Hydraulic Fluid. Start the sprayer at just enough
pressure to operate the uid section. Run the sprayer at
this low pressure for at least 5 minutes. This removes
air from the system. Check the uid level after this
procedure. Do not over-ll.
NOTE: When replacing the hydraulic lter during a uid
change, it may be necessary to add up to one
additional quart of hydraulic uid.
3. The hydraulic system has an external, replaceable
hydraulic lter. Change the lter every twelve months.
4. The hydraulic pump should not be serviced in the eld.
If service on the hydraulic pump is required, it must be
returned to Titan.
Maintaining the Fluid Section
If the sprayer is going to be out of service for an extended period
of time, it is recommended that following cleanup a kerosene and
oil mixture be introduced as a preservative. Packings may tend
to dry out from lack of use. This is particularly true of the upper
packing set for which upper packing lubricant Piston Lube (P/N
314-480) is recommended in normal usage.
If the sprayer has been out of service for an extended period of
time, it may be necessary to prime the pump with solvent. It is
extremely important that the threads on the siphon tube/hose
coupling are properly sealed. Any air leakage will produce erratic
operation of the sprayer and may damage the system. The up
and the down strokes should be approximately equal in time (one
should not be faster than the other). A fast up or down stroke
may indicate air in the system or malfunctioning valve or seats
(see the Troubleshooting section).
